The Port Theatre at 132 Montreal Road in Cornwall, Ontario, first opened on December 26, 1941, as the Roxy Theatre — a 775-seat movie palace that served the city through the golden age of cinema. It closed briefly in 1961, reopened in 1963, and was renamed the Port Theatre on July 13, 1966. After years of evolving use, the venue was revitalized by owner Larry Sylvain and now operates as a live performance space and cinema, anchored by its Art Deco marquee and a reputation as one of Cornwall’s most recognizable landmarks.
The current configuration seats approximately 450, with a full-sized stage, an upper balcony, professional lighting and sound equipment, and a fully licensed bar. Programming mixes live music concerts — including tribute shows and touring acts — with comedy nights, theatrical performances, community events, and special film screenings. The acoustics were designed for sound from the beginning, and the room retains the proportions and character of a mid-century theater. At 450 seats, every show feels personal, and the balcony seating adds a second perspective that most small venues cannot offer.
Cornwall sits on the Upper St. Lawrence River in eastern Ontario, close to the Quebec border and roughly midway between Montreal and Ottawa. The city has a population of around 47,000 and a community arts scene that the Port Theatre both reflects and energizes. Montreal Road runs through the commercial heart of the city, with restaurants and services nearby. From Upstate New York, Cornwall is accessible via the Seaway International Bridge from Massena — a drive of roughly two hours from Syracuse and just over three from Albany.
The Port Theatre is a survivor — an Art Deco movie house that reinvented itself as a live performance venue without losing the character that made it special in the first place. For Upstate audiences in the northern corridor, it offers a cross-border option with genuine charm, a manageable scale, and the kind of eclectic programming that keeps regulars checking the calendar. It is the smallest venue in this part of Ontario, and that is precisely its strength.
